Increase resolution

Good evening,

I have a rotator V3 + controller v2 + hamlib + gpredict.

All is fine. But I see that the rotator move by step of 1°. Is it possible to configure something to have a resolution less than 1° ?

In fact, is it possible to do that for exemple :

AZ 150,5° EL 42.4° ???

Thanks, F4FLU

I’m not sure if a finer resolution is possible, but let me turn the question around - is it necessary? The size of antennas you would be able to put on there are going to have a wide enough beamwidth to be off by a number of degrees and still be fine…

Yes, I know that 1 ° is more than enough for a yagi, but I would want just to know if the rotor could work as a telescope frame : the engine of follow-up works permanently and not by surge.

For telescope tracking you would need more functionality that existing (let alone the accuracy that needs to be in the order of arcseconds):

  • Tracking in sidereal, solar, lunar, planetary, comet and custom modes
  • Guiding pusle capabilities for fine tuned tracking
  • Sync and slew capabilities (software implemented)
  • Advanced: Periodic error correction
  • Advanced: Polar alignment and setup abilities

That said, I know that @azisi (the main dev of our rotator) is eyeing some of this functionality

Hey, are you using DC or Stepper motors?
Also you can check this V3.1 DC rotator about rotator resolution.

I use stepper motor,
